[SingCERT] Alert on global spread of Ransomware Petya
on 27th June 2017, SingCERT was alerted to the global spread of a ransomware inspired by WannaCry, identified as Petya.Petya is more dangerous and intrusive as its behaviour is to encrypt the Master File Tree (MFT) tables for NTFS partitions and overrides the Master Boot Record (MBR) with a custom bootloader to display a ransom note and prevents victims from booting up. The new Petya version also included a similar SMB work based on the EternalBlue exploit.
Petya spread via email spam with booby-trapped Office documents.The documents, once opened, will download and run the Petya installer and execute the SMB worm to spread to other computers.
Affected system
The following Microsoft operating systems are currently suspected to be vulnerable
•Windows 10
•Windows RT 8.1
•Windows 8.1
•Windows 7
•Windows XP
•Windows Vista
•Windows Server 2016
